Hi all, 

i m not clear about AWGN channel . most paper and book consider that 
channel is Gaussian and it has zero mean and N0/2 noise spectral 
desnsity for eatch side. 
i just clear channel is random it has normal valriable(zero mean) and 
noise
	what is the meaning of two sided spectral density is it transmitter 
side as well as receiver side noise level.
	What is the relation between  AWGN channel and rayleigh fading channel 
?
	could u possible to little bit implent what exactly that........if 
possible give a example.
	thanks in advance.
